Letters IPatent No. 101,182, dated March 22, 1870; lmtedated-Ma1'ch 16, 1870.

*w* IMPROVEMENT IN MACHINE lPOR MAKING- PUMP-BUCKETS The Schedule referred to in these Letters Patent and making part of the same To all whom tt may' concern:

Be it known that I, J oHN F. TEMPLE, of the city of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Machine Afor Making Buckets for Wgoden Pumps, and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention I'will proceed to describe it.

l igure l represents a general plan of the machine, showing places where different devices are affixed to the frame.

Figure 2 is the front elevation, and

Figure is the side elevation of part A ofthe Inachine.

Figure 4 represents in perspective the curved knife j.

Figure 5 is the side elevation of part B of the ma-`v chille.

Figures 6 and 7 represent rest M in different positions, connected with part B.

. `Figure 8 is the side elevation of part C of the machine.

Figure 9 is the side elevation of the block of the bucket before it is put through the machine, and

Figure 10 represents the bucket when finished.

Figure l1 is the cutter-head g.

The nature of my invention consists in several devices mounted ona frame, and constituting a machine for the purpose of manufacturing pistons, commonly called buckets or suckers, for wooden suction-pumps, which have heretofore been almost exclusively made by hand.

The block, lirst shaped as represented on lig. 9, viz:

rounded, provided with a seat for the leather, and nartially bored through the butt end, is gradually undergoing changes on different parts of the machine, marked by letters A, B, and C, until it assumes theshape `shown ou fig. 10, `and becomes ready to receive the leather and the'vaIVe, and, after being connected with a piston-rod, to go-into the tubing of the pump.

The machinery performing these different operations is mounted on a strong frame, A A', the cutter-heads in partsiA and B being operated by pulleys D D D, connected by a belt with pulley E, while the cuttingtool in part C is operated by pulleys F F and belts G G', the power being applied to pulley W.

Part A of the machine consists of a slide or table, a, secured to frame a', set in grooved plates x 21:, and operated up and down by a combination device consisting of chain of levers b, lever il', rope c, and hand lever d, or by some other suitable device.

The slide a on the top is provided with raised dovearch in said bucket-block, each set consisting of two square cutters t i to cut out the recess, and one curved knife j to cut out the arch, which operation is performed on both sides of the block at the same time. In the operation the slide a is gradually raised, the block f passing between the cutter-heads g' g'.

Part B of the machine consists of a table, H, horizontally sliding in grooves on the supporting-arms I I.

Standard J, placed in grooves on and secured by a pin to-t he table H, bears at the topa device, K, consisting of lever k, movable pin Z, and coil spring m, which device serves as a clamp to secure block f, after it has been arched, on part A, in a vertical position on the table H, for the purpose of bringing it by hand to the cutters L tted iu the hub of shaft It', and boring a round hole, o', in the arch of said block, part tof the standard J serving as a rest to the bucke`t-block f, between which and the said rest a wooden block, t', is inserted. 4

To the same table H a rest, M, is hinged, which rest is shaped as represented on figs. 6 and 7, and has a particular destination, as will be hereinafter fully explained.

After the round hole O' in thc arch of the bucket is bored the block is removed to the part C of the machine, for the purpose of cutting in it a square hole below andin connection with the round hole already bored, and thus completing the opening O of the bucket, as shown on fig. 1 0.

This part of the machine consists of a table, N, secured to the frame-A A by set-screws n n, and provided with arm P supporting a pulley, p, and a shaft to which a cutter-head, Q, provided with square cutters q, is aixed.

Carriage It, on which standard S `is affixed, moves.

in grooves on the table N, and is fed by the endless hand-screw rr affixed to the table N, and operating in a nut, t, of the carriage R, and a clamping device similar to the device K is aixed at the top of the stand ard S, to keep the bucket-block f placed ou thc carriage It in a vertical position. A. fork, s, atxed to the standard S, serves as a back rest to the bucketblock f.

When the opening O in the arch of the bucket is ready, the block f is taken back to' the part B of the machine, where the standard J is removed and the rest M is placed on the table, as shown in figs. 6 and 7 Then an ordinary augur is substitutedin place of the cutters L, and the block f placed on the rest. M, as on g. 7, and a hole through the top ofit is bored to accommodate the bucket-rod y. Then a gimlet is substituted in place of the anger, and the block f is placed on the rest M in a position at a right angle -to its former position, and a hole, lv, is bored inthe top of it to accommodate the pin .securing the bucket to the rcd y. rlhis last operation finishes the bucket, to which then the leather andthe valve are attached, and it is ready to go into the tubing of the pump.

'.lhus, `the bucket-block, by being operated upon on different parts of the machine, is completed by mechanism, and is, therefore, true in all its parts` Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is

1. The rest M, constructed and arranged as described, Whereby it is adapted to fit upon the plate I, and to be used for holding the block f while the hole is being bored in its upper end to receive the rod y, as set forth.

2. Thecombination of the cutter-beads D D, provided with the knives j and i, and the vertically-ad- V justable table a. and `sliding-block holder c, all con structed and arranged to operate substantially as described.

3. The plate a mounted on the adjustable frame a', and carrying the ysliding clamp c, when arranged to operate in combination with the cutter-heads g g, substantially as shown and described.

4. The part B, consisting of table H, standard J with device K, and cut-ters L or angers, all arranged and operating substantially as and in the manner herein described and specified. 'l

5. The part C, consisting of table N, arm P, cutterhead Q, carriagelt with standard S, and hand-screw r, all arranged and operating substantially as herein set forth and speciiied.-

6. The machine, constructed substantially as described, 'consisting of the parts A, B, and C, arranged to operate as and for the purposes herein set forth.

JOHN F. TEMPLE.
